CLOSURE ACTUATING MECHANISM Filed Aug. 29 1952 2 Sheets-Sheet 1 March 19, 1957 R -r CLOSURE ACTUATING MECHANISM 2 Sheets-Sheet 2 Filed Aug. 29, 1952 United States Patent This invention relates to.a closure actuating mechanism or. stay bar assembly for use with. a. projected type of window or awningtype of.window,,a1though not necessarily. so limited.

Inprojected type, ofz'window, itis quite desirable to actuate the window into, a position suchfithat both the inside andfthe outside of 'the window may be washed or the window may bereglazed'from the inside jwithout removing the window sash. With the use of' conventional operators, the outward swinging movement of the projected window sash is limited, 'so that it"is inconvenient and for all practical purposes'impractical' to attempt to wash the outside of the' window fromthe inside.

A'nrobject of'this invention is to provide ajprojected type .of window actuated'by aJstaybar assembly thatma'y be detached from the window, so as to permit the window 'to be' actuated 'beyondthe operative'range of thest'aybar assembly into a position such'that both sides of the window maybe washedtfrom the inside without detaching or removing the window sashfrom the'window'frame or window. opening.

Another object of this invention is to providea removably mounted stay bar assembly. for a window wherein the stay bar assembly consists of two pivotally'connected members, one of which is removably attached to the window and the other is providedwith a plurality of notches adapted to hold the windowopen invarious angular positions, as will appear-morefully fromthe description that follows.

Other. objects and advantages reside. in the construction of parts, the combination thereof-and the rmode of operatioini as will become more apparent from the following description;

Referring to the drawings,

Figure 1 is aperspect-ive view of awindow shown in one open position..

Figure 2 is another perspective view of the window shown in Figure 1, showing the stay bar actuator disconnected from the window, so that the window may be moved beyond the operative range of the stay bar actuator, so that the window may have the outside washed from the inside of the window.

Figure 3 is a fragmentary enlarged side elevational view of the actuator mechanism with parts of the window and the window frame shown in cross section.

Figure 4 is a top plan view of the actuator mechanism shown holding the window sash in closed position, parts of the window being shown in section and broken away.

Figure 5 is a cross sectional view taken substantially on the line 55 of Figure 4, without disclosing the brackets.

Figure 6 is a fragmentary view of a pivotal attachment for slidingly mounting the top of the movable window frame or closure in a channel in the main frame.

In the drawings, the reference character 10 designates a frame of a window provided with a closure 12 that is pivotally mounted on a pair of brackets or arms 14, only one of which has been shown. The brackets 14 are pivotally attached at '16 to the stationary window frame and pivotally attached to the window sash orclosure 12 near the center thereof. The closure 12 is also provided with a pivotal attachment to a member mounted for sliding movement in the slot 18, aswill appear more fully later.

The pivotal mounting of the top of thewindo'w closure has been shown intFigure 6, wherein a bracket 20 isi'attached to. the top of thewindow closure by screws '22. A slottedl member 24. is fixedly attached to theframe. The window frame is 'provided with; a verticallydisposed slot or groove 32 underlying the slot"18'"in member 24. The slot in member 24 overlies the groove32. The outer surface of member 24 is'preferably flush with the adjacent portion of the window frame. A slidably mounted rivet26is attached to a flange28 of the bracket 20 and supports a washer 30'located in thechannel 32 underlying the slotted member 24,;as'best seen in Figure 6. As the lower portion of'the window sashlz swings outwardly, the brackets 14 have their upper endsgprojecting outwardly and the top of the window is' lowered. The rivet 26 then slidesdownwardly in the slot in member24. It'may be lowered into a horizontal position, as shown in Figure 2, when the pivot; including the rivet 26, is in the lowermost position of the slot-in memher 24.

Asmay best be seen-by referring to Figures 3- and 4, the movablewindow sash-or closure'12 is provided with two brackets 40 and 40a, the bracket 40 having a vertically disposed slot 42 andthe bracket40iz havinga'n aperture 42a. A stay bar assembly 5tl'is rem'ovably 'attached tothe brackets'40 and'40a; Thisstay bar assembly includes a comparatively short'bar or link 52 provided with a cylindrical cavity or recess 54'adjacentone end thereof. This cylindrical cavity is provided'with a shoulder against which a compression spring -is seated. Thisspring 8t? surrounds a reduced portion 70 of a pin 72'. The pin 72 terminates in a knurled cylindrical head "74. A kerfed nut 53 'threadedly engages the threads 56 on the end of the reducediportion 70. This not 58, havinga cylindrical perimeter, is normally positioned in the aperture 42a in the bracket40a.

The spring 84) biases or urges the pin 72'to the right, as viewed in Figures 4 and 5, so as to hold the cylindrical nut 58 in the aperture 42a in the bracket 40a. In order to remove link 52 from the sash 12, it is merely necessary to grasp the knurled cylindrical portion 74of the pin 72 and pull it toward theleft, as viewed in Figures 4 and 5, to compress the spring 80, so as to cause thenut 5% tube retracted into the cylindrical cavity 54 -to. permit removal of the link from the brackets =40 and 49a. The link 52 may be connected to the brackets by again retracting the nut 58 into the recess 54, so as to permit the insertion of the pin 72 into the slot 42 in the bracket 46*, and when the nut 58 is aligned with the aperture 42a in the bracket 40a, the pull exerted upon the cylindrical portion 74 may be released, so as to permit the link 52 to lock in position.

The bar 52 has pivotally attached thereto a notched bar 82 by means of a pivot 84. The notched bar 82 is provided with a plurality of notches 86 on the under side thereof, adapted to engage the margin of an aperture in a bracket 90 attached by suitable screws 92 to the window sill 94. The outer end of the bar 82 is provided with a suitable handle for use by the operator in actuating the stay bar assembly. In closing the window, the bar 52 projects through the aperture in the bracket 90, so as to permit the pivotally mounted notched bar 82 to be actuated at right angles about the pivot 84 into the position shown in Figure 4, at which time the bar 82 is held in position by a stop 102. The length of the bar 52 depends upon the width of the window sill. 'The length is preferably such that it extends from the window through the bracket 90 a distance sufficient to lock the window sash in closed position when the bar 82 is adjusted into the position shown in Figure 4.

The bar 82 and the notches therein are'preferably so dimensioned that the window sash may be adjusted into any suitable open position for ventilation. However, it is not practical by the use of the window sash actuator to actuate the window sash into the horizontal position shown in Figure 2. That being the case, the actuator bar assembly is detached from the closure by merely pulling upon the knurled head 74 of the pin 72 to disengage the brackets 40 from the actuator. The window ,sash 12 may then be manually adjusted into the position shown in Figure 2.

' In the event a screen is used on the inside of the and aligned withthe aperture and the slot of the brackets,

window sash, it is merely necessary to provide an opening or passage in the lower margin of 'the screen frame for the actuating mechanism, consisting of the bars 52 and 82. By this arrangement, it is possible to actuate the closure from open position into closed position, or vice versa, without removing the screen.

Although the window sash has been shown as con- -sisting of a single window pane, it is not necessarily so limited. Furthermore, the actuator bar assembly may be used with any other suitable type of closure, as for example, a metallic closure, used in closing any type of -opening.

Although the preferred embodiment of the device has been described, it will be understood that Within the purview of this invention various changes may be made .in the form, details, proportion and arrangement of parts, the combination thereof and mode of operation, .which generally stated consist in a device capable of carrying out the objects set forth, as disclosed and defined in the appended claims.
